摘要： A process for recovering hydrogen-rich gases and increasing the recovery of liquid hydrocarbon products from a hydrocarbon conversion zone effluent is improved by a particular arrangement of a refrigeration zone, a pressure swing adsorption (PSA) zone, and up to two separation zones. The admixing of at least a portion of the tail gas from the PSA zone with a hydrogen-rich gas stream recovered from a first vapor-liquid separation zone results in significantly improved hydrocarbon recoveries and the production of a high purity hydrogen product. The process is especially beneficial in the integration of the catalytic reforming process with vapor hydrogen consuming processes such as catalytic hydrocracking in a petroleum refinery.
